Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a technique for driving away wild birds that fly to a field, an orchard, etc., or inhabit the surrounding area and feed on crops or seeds after sowing.
[0002]
[Prior art]
Traditionally, in the cultivation of rice and rice, a scarlet child is set up to be a human figure, a ribbon that glitters is twisted and stretched, and the sun rays are diffused by shaking in the wind. There were a variety of things, such as putting a thin thread that was invisible and touching the body of the flying harmful bird as a threat and preventing the flying, but all were less effective. For this reason, for example, as disclosed in Japanese Patent Laid-Open No. 5-123093 Generating threatening sounds, threatening with models of monsters and raptors such as Japanese Utility Model Laid-Open No. 5-70281 and Japanese Patent Application Laid-Open No. 2001-190212, and Japanese Patent Application Laid-Open No. 8-9866 and Japanese Patent Application Laid-Open No. 10-248472. A bird damage prevention device has been developed that prevents flying by a magnet as in the Japanese Patent Publication No. Gazette, or drives away such as in Japanese Utility Model Publication No. 7-17083.
[0003]
[Problems to be solved by the invention]
However, those that generate intimidating noises are annoying to the residents in the neighborhood, and those that threaten with a model of a monster bird or bird of prey are immediately accustomed like Scarecrow, and the prevention of flying by magnets has a narrow range of effects. Even if a fishing rod as disclosed in Japanese Utility Model Publication No. 7-17083 is irregularly decelerated and rotated by an automotive wiper motor, the bird quickly gets used and the harmful birds remain in the rod. Further, when a sound generator or a movable device is used, a power source is required, but it is usually a problem that a commercial power source is not familiar, and it is required to maintain the effect over a wide range.
[0004]
The present invention solves such a conventional problem, and does not adversely affect the surrounding environment, and can prevent bird damage that can easily and continuously exert effects in fields, orchards, etc. The purpose is to provide a device.

Has the effect of threatening.
[0015]
Embodiments of the present invention will be described below with reference to the drawings.
[0016]
【Example】
( Reference Example 1)
As shown in FIG. 1 and FIG. 2, the bird damage prevention apparatus 1 fixes the drive part 3 which incorporates an electric motor to the upper end of the column-shaped support | pillar 2 using a steel pipe, and lowers it to the place which needs this apparatus, such as Inada. And erected vertically. A rotating plate 5 is attached to the upper surface of the drive unit 3 by being connected to a built-in motor rotating shaft 4 so as to coincide with the axis of the column 2. Then, two rotating bodies 6 having a predetermined length in which a piano wire is formed in a rod shape having a required thickness are fixed so as to protrude from the peripheral end of the rotating plate 5 so as to face the axis of the support column 2. A bird of prey model body 7a which also serves as a weight is provided at the tip of the rotating body 6 as a threatening member 7, and is bent in a drooping shape when stationary and in an arc when rotating. Further, a plastic film on which aluminum is vapor-deposited is reflected as a threatening member 7 at various places on the rotating body 6 as a fluttering ribbon 7b, and a permanent magnet as a repellent is attached. In addition, the support column 2 below the drive unit 3 is provided with a microphone 8 that collects the sound of pests and a speaker 9 that generates repellent sound. Between the microphone 8 and the speaker 9, the photovoltaic power generation element 10 emits sunlight. Arrange for convenient reception. A box operation unit 11 is provided below the support column 2, a power storage device such as a storage battery and a commercial power supply switch that stores electric power from the photovoltaic power generation element 10 and supplies it as needed, a microphone 8, A sound collecting amplifier 13 constituting a sound generating circuit 12 with the speaker 9, a filter 14 for selecting the collected pest calls, a sound board 15 having a pest repelling sound, and a repelling sound amplifier 16 are provided. ing.
[0017]
The operation of each part in the above configuration will be described sequentially. Harmful birds such as sparrows, crows, and pigeons do not fly directly to Inada from a distance, but first stay in nearby electric wires, fences, and sometimes scarecrows, and watch and threaten the surroundings. I make a loud cry at that time. When this cry is caught by the microphone 8, the electric motor of the driving unit 3 is operated to rotate the rotating body 6 fixed to the rotating plate 5. At the same time, the sound of the bird of prey on the voice board 15 and the repelling sound reverberate from the speaker 9, and the rotating body 6 swings with the bird of prey model body 7a and the ribbon 7b that flutters and flickers while fluttering, and moves in a positive direction. I do. Pests quickly dissipate from fear of hearing and visual and instinctive fear and disgust of objects that turn with anti-curvature movement. Further, even when the solar radiation is weak due to cloudy weather or the rotation of the rotating body 6 is weak, there is a slight anti-curvature movement, so the decrease in the diffuse reflection of the light beam of the ribbon 7b is small, and the movement of the reflective raptor model 7a is real There is no such thing as a pest that gets used to the rotating body 6. Moreover, since the drive part 3 uses the electric motor, it is easy to make the rotation adjustment of the rotary body 6 irregular, and it can prevent a harmful bird from getting used to it.
[0018]
Note that the microphone 8 that collects the call is more effective if it is directed in the direction of the electric wire or fence for each site. Moreover, the material shape of the rotating body 6 may be formed in a plate shape, not limited to a rod shape, such as bamboo or carbon fiber, depending on the scale of the apparatus.
[0019]
( Reference Example 2)
Bird damage prevention apparatus 17 shown in FIG. 3, the rotating plate portion of the drive unit with a built-in electric motor provided at the upper end of the column in Example 1 obtained by the Saponiusu windmill 18, the same portions as in Reference Example 1 the same reference numerals The description is omitted. With this configuration, the electric motor becomes a generator when the rotational speed of the wind reaches a predetermined value, and is stored in the storage battery together with the electric power from the solar power generation element 10. And if there is a rotating wind power that is not charged, but the pests fly, only wind power is used. If rotation by wind power is insufficient, the motor that is also the generator is driven by the power of the storage battery with commercial power and natural energy. To do.
[0020]
In this way, the power generated by natural energy fluctuates greatly. For example, harmful birds have a strong appetite early in the morning or before sunset, and crops are susceptible to damage during this time. However, the amount of power generated is small because the sunlight during this period is weak and the wind power is also weak. For this reason, it is effective to provide a storage battery to accumulate surplus power from wind power that can be generated even when the sunlight is strong during the blue sky or at night, so that it can be used whenever necessary.
[0021]
The windmill may be a propeller type windmill.
[0022]
( Reference Example 3)
FIG. 4 shows a flexible long bar-like rotating body in Reference Example 1, which is a solid bar, and is suspended from the upper end of the column with a thread-like material so as to be pivotable. Similar to Reference Example 1 Parts are denoted by the same reference numerals and description thereof is omitted. In other words, the bird harm prevention device 19 includes an electric motor 22 externally attached to the column 20 by rotatably mounting a cylindrical rotating wheel 21 at a position at a required height from the ground surface on the lower outer periphery of the column-shaped column 20 erected. To drive the belt. The support column 20 is vertically erected by embedding the lower end where necessary, and a branch line 20a is stretched from the upper end to the ground surface and fixed by an anchor 20b. Two rod-shaped rotating bodies 23 of a predetermined length are fixed to the outer periphery of the rotating wheel 21 so as to protrude opposite to the axis of the support column 20, and the auxiliary ring 24 is rotatable on the outer periphery of the support column 19. It is attached and the tip of the rotating body 23 is tied and held horizontally by a hanging wire 25 of a piano wire that is thin and strong like a fishing line. Thus, since both ends of the rotating body 23 are held by the rotating wheel 21 and the suspension line 25, the rotating body 23 can be made considerably long. Therefore, the support column 20 is also reinforced by stretching the branch line 20a. The rotating body 23 is provided with a bird of prey model 7a as a threatening member 7 and a ribbon 7b of a light reflecting plastic film at important points.
[0023]
In the above configuration, when the speaker 9 sounds and the electric motor 22 rotates the rotating wheel 21, the rotating body 23 turns while inspiring the bird of prey model body 7a and the ribbon 7b. Still, when the harmful bird approaches the rotating body 23, it comes into contact with the hanging line 25 that is difficult to see, and once the foreign object contacts the body, the harmful bird never approaches again. Moreover, since the rotary body 23 can be made quite long, the effect over a wide range can be exhibited.
[0024]
(Example 1 )
In the example shown in FIG. 5, the connection of the rotating body protruding on the outer periphery of the rotating wheel in Reference Example 3 can be moved up and down, and the shape material of the suspension line that holds the protruding tip end from the upper end of the column has elasticity. The same parts as those in Reference Examples 1, 2, and 3 are denoted by the same reference numerals, and the description thereof is omitted. That is, the bird damage prevention device 26 is a rod-shaped rotating body having a predetermined length on the outer periphery of a cylindrical rotating wheel 27 that is belt-driven by an electric motor 21 that is rotatably mounted on the lower outer periphery of an upright columnar column 20. Two of 28 are protruded opposite to the axis of the column 20 and connected in a hinge-like manner so as to be movable up and down. The auxiliary ring 24 above the column 19 and the tip of the rotating body 28 are connected to a suspension coil 29 of a tension coil spring. And hold it horizontally.
[0025]
With this configuration, when the rotating body 28 turns, it moves positively in the vertical direction due to the spring of the tension coil spring, so that threat to harmful birds is effective. Further, even if the connection between the outer periphery of the rotating wheel and the rotating body is fixed, the same effect can be exhibited if the material shape of the rotating body 28 is flexible.
[0026]
【The invention's effect】
As is clear from the above embodiments, according to the present invention, a flexible long rotating body is rotatably supported at the upper end of a standing column, and a bird of prey model body and a light reflecting material are provided at important points. By attaching and flexing downward and turning, the long rotating body turns and rotates, causing anti-curvature movement and irregular movement, strengthening the threat to pests and It is possible to provide a harmful bird prevention apparatus that can prevent habituation.
[0027]
In addition, a long rotating body is made into a rod shape, and its tip is suspended from the upper end of the column by a thread-like material, and the other end is pivotally supported around the column to attach a bird of prey model or a light reflector. By swirling, a pest control device that can give a sense of threat together with a threat by contacting a difficult-to-view thread material together with a visual threat and can enhance the effect of eliminating the approach of the harmful birds is obtained.
